Specification of Letters Patent.

Application filed August 18, 1916.

To all whom it may concern:

Be it known that we. Bnnrvrmnn B. HART- Lnn and RUDOLPH C. HARTLEB, citizens of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Automatic Baby-Carriage Fans, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved automatic baby carriage fan and has for its primary object to provide a very simple and effective mechanism for imparting a vertical swinging movement to a fan supported over the carriage.

It is another object of the invention to provide improved means for mounting the operating mechanism whereby the device may be easily and quickly applied to or removed from baby carriages, go-carts, toy wagons, and similar vehicles.

The invention has for another important object to provide improved means for mounting and adjusting the fan supporting or carrying rod so that it can be disposed out of the way in placing the infant in the carriage or removing him therefrom, and also adjusting the support to properly position the fan over the carriage.

With the above and other objects in view, our invention consists in the novel features of construction, combination and arrange ment of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a side elevation showing our improved automatic fan applied to a baby carriage; i

Patented Mar. 13, 1917.

Serial No. 115,893.

The ends of this base bar, as shown in Fig. 2, are flanged for engagement with reinforcing ribs or cleats on the inner face of the carriage wall. The bar 5 is provided with a short vertical slot 7 therein through which the threaded bolt 8 is disposed and is vertically adjustable. A wing nut 9 is threaded upon the inner end of said bolt and, to the outer end thereof, a hook 10 is fixed for engagement over the upper edge of the carriage. By adjusting the nut 9, the hook may be drawn into tight clamping engagement with the carriage wall.

A bracket 11 is fixed at one of its ends to the standard 6 and has a vertically disposed portion extending in spaced parallel rela tion to said standard. A shaft 12 is mounted to rotate in the standard and said bracket, and upon this shaft a sprocket wheel 13 is suitably secured. This wheel is connected by means of a drive chain 14 to a larger sprocket wheel 15 fixed to the hub of one of the front vehicle wheels of the carriage. Upon the inner end of the shaft 12, a disk 17 is suitably secured and is provided with an eccentrically disposed wrist pin 18. Immediately below said disk, a horizontally disposed arm 19 is fixed to the upright or standard 6, and to this arm the lower end of a vertically disposed bar 20 is secured. In the upper end of said bar, a pin or stud 21 is fixed. An arm 22 is provided with a longitudinally extending slot 23 to receive the pin 21, said arm sliding freely between spaced washer plates 24 engaged upon said pin. One end of the arm 22 is loosely mounted upon the wrist pin 18 and held in connection therewith by means of a suitable key indicated at 25, a similar key 26 disposed through the end of the pin 21 also preventing shifting movement of the arm 22 longitudinally on said pin.

A rod 27 is slidably engaged in the other end of the arm 22 and extends inwardly and at right angles to said arm. A sleeve 28 projects from the inner faceof the arm 22 and is integral therewith or secured to the same in any approved manner. A pin indicated at 29 projects from the other end of 33 is secured by means of the set screw 34 on the outer end of the rod 27, and a clamping screw 35 is threaded in the sleeve 28. whereby the rod may be securely held against turning movement in the arm 22.

The inner end portion of the rod 27 is angularly disposed, as at 36, to extend longitudinally in a rearward direction over the carriage, and upon the inner end of this portion 36 of the rod a stop shoulder 37 is provided. A sleeve or tube 38 is adjustably engaged upon the longitudinal end portion 36 of the rod and carries a set screw 39, whereby said sleeve may be securely fixed in its adjusted position upon said rod. he sleeve 38 is formed upon one end with a suitable socket to receive the shank of a fan, indicated at F, and the clamping screw 40 is threaded in the wall of the socket to engage said shank, whereby-the fan may be detachably held in connection with the sleeve. The inner longitudinally disposed end portion of the rod 27 may be disposed at any desired angle over the carriage,by loosening the screw and the screw 32 on the collar 30 so that the rod 2.7 may be turned in the end of the arm 22. These screws are then properly tightened, it being understood that one of the shoulders 31 on the collar 30 is in contact with the pin 29. In this position, the angular end portion 36 of the rod projects rearwardly over the carriage. In placing the infant in the carriage or removing him from the same, the screw 35 is loosened and the end 36 of the rod 27 is swung upwardly and forwardly until the other stop shoulder 31 on the collar 30 engages with said pin. The fan F having been fixed in the sleeve 38, the rod is returned to its former position and the screw 35 then tightened thereon. As the carriage is pushed or propelled, rotation will be transmitted to the shaft 12 from the front wheel of the carriage, and the arm will be shifted longi-- tudinally and vertically oscillated upon the pin 21 by reason of its eccentric connection to the disk 17. In this movement of the arm, it will be rear ily seen that ,as the rod 27 is rigidly fixed thereto, the fan F will be vertically swung or oscillated, and will agitate the air and direct the air toward the infant in the carriage.

In some carriage constructions, it may not be possible to apply the device by means of the base clamp above described, and we have, therefore, illustrated in Figs. 5 and 6 of the drawing another form of support which may be used where the wall of the carriage is flush on its inner and outer faces and not provided with reinforcing ribs or cleats. In this construction, a clamp of substantially inverted U-shape form, indicated at 41, is engaged over the upper edge of the carriage wall and a set screw 42 is threaded in the arm of the clamp which is disposed upon the outer face of the wall for binding engagement with said wall to hold the clamp in its applied position. An upstanding loop is integrally formed upon the medial portion of the clamp and, in the same, the base bar 5 is siidably engaged. A set screw et-It is also threaded in one side of said loop for binding engagement with the base bar to hold the same in its longitudinally adjusted position. The several means which we have shown and described for mounting the mechanism upon the carriage are merely illustrative, and it is to be understood that various other means for clai'nping or mounting the supporting frame upon the carriage may be substituted in lieu thereof.

From the foregoing description, taken in connection with the accompanying drawing, the construction and manner of operation of our invention will be clearly and fully understood. The device may be easily and quickly applied to or removed from the can riage and automatically operates the fan or toy in the movement of the vehicle. The fan may be of various shapes and ornamental forms and, if desired, a number of fans may be suitably arranged upon a common rod or stall? secured in the sleeve 38.

While we have shown and described the preferred form, construction and arrange ment of the several elements employed, it is also to be understood that the same are susceptible of considerable modification therein and we, therefore, reserve the privilege of resorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

The sprocket 15 may be clamped or otherwise suitably attached to the hub of the ordinary carriage wheel without requiring any structural changes in the latter. The oscillatory fan F also obviates the possibility of flies or other insects annoying the infant.

Having thus fully described our invention, what we desire to claim and secure by Letters Patent is 1. The combination of a support, a shaft mounted in the support, an arm slidably supported intermediate of its ends and ec-' centrically connected at one of its ends to said shaft, means for attaching a fan to the other end of said arm, and means for rotating the shaft, whereby the arm is oscillated to impart a bodily movement to the fan.
